Best HVAC Systems for Larger Homes

Ensure Optimal Cooling For Your Home With The Right-Sized HVAC System

Phoenix, AZ, is known for its beautiful scenery, vibrant culture, and scorching heat. The Valley of the Sun is home to luxurious neighboring areas like Biltmore Heights, Paradise Valley, Encanto, Chandler, Scottsdale, and Fountain Hills, known for their estates and large homes.

Homeowners in these areas enjoy spacious living areas, grand architecture, and stunning outdoor spaces. However, the grandeur of living large comes with its own challenges, especially when it comes to keeping a comfortable indoor temperature during the hot Phoenix summers.

To ensure your home remains a cool and comfortable oasis, you need a strong and efficient HVAC system tailored to every square foot of your living space.

The size of your HVAC system is critical; if it is too small, it will struggle to cool your large home, resulting in uneven temperatures and excessive wear and tear on the system. If it’s too large, you may notice energy efficiency issues, leading to high utility bills and a larger carbon footprint.

So, how do you make sure your AC is the right size for your home, and how can you use zones to keep your large home comfortable without wasting energy?

How Are HVAC Units Sized?

We use a process called Manual J load calculation to determine the heating and cooling needs of your house. This calculation considers various factors, including square footage, climate zone, insulation quality, window size, and occupancy.

HVAC systems are sized based on their capacity, which is measured in British Thermal Units. One BTU is the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. For cooling, the capacity is also sometimes measured in tons, where one ton equals 12,000 BTUs.

An average home requires about 20 BTUs per square foot for cooling. However, this is a rough estimate and may not be accurate for all homes.

Homes in Biltmore Heights, Paradise Valley, Encanto, ChandlerScottsdale, and Fountain Hills range from 2,500 to 6,000 square feet. A 3,000-square-foot home would require 60,000 BTUs, which equals 5 tons.

How Do HVAC Zones Work?

HVAC zoning is a method used to divide a home or building into different areas or “zones,” each of which can be controlled independently in terms of heating and cooling. This approach aims to enhance comfort and energy efficiency by allowing for customized temperature settings in different parts of a building.

HVAC zoning divides a home into zones with individual thermostats, leading to increased comfort, energy efficiency, flexibility, and system longevity. It works by installing motorized dampers in the ductwork and a central control panel.

The benefits include:

  • Increased comfort: Tailored temperature settings for each zone
  • Energy efficiency: Prevents wasted heating or cooling energy
  • Flexibility: Customizes the temperatures of different parts of your home
  • Longevity: Reduces wear and tear on HVAC unit

Additional Tips To Improve Airflow

Maintaining a consistent temperature throughout a large home can be challenging, but there are several things you can do to prevent hot and cold rooms and improve airflow.

Here’s how you can create a more balanced home climate:

  • Install a zoning system by upgrading to a smart thermostat.
  • Use ductless mini-splits, which can be controlled individually.
  • Add or replace the insulation in your home and seal air leaks.
  • Get double-pane windows and hang thermal curtains.
  • Schedule regular HVAC maintenance and replace air filters every one to three months.
  • Make sure your vents and registers are open, clean, and not blocked by furniture or window treatments.
  • Install ceiling fans. These are great for circulating air; make sure it rotates counter-clockwise in the summer and clockwise in winter.
  • Add exhaust fans in bathrooms and kitchens to remove stale air, moisture, and odors.
  • Get a smart thermostat so you can monitor your home’s temperatures in real time.
